Long long long ago Go permitted writing func F() in one file and writing func F() {} in another file. This was removed from the language, and that is now considered to be a multiple definition error. Gccgo never caught up to that, and it has been permitting this invalid code for some time. Stop permitting it, so that we give correct errors. Since we've supported it for a long time, the compiler uses it in a couple of cases: it predeclares the hash/equal methods if it decides to create them while compiling another function, and it predeclares main.main as a mechanism for getting the right warning if a program uses the wrong signature for main. For simplicity, keep those existing uses. This required a few minor changes in libgo which were relying, unnecessarily, on the current behavior. Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed to mainline. Ian
